P. SCHORNO. GEAR OPERATING DEVICE. APPLICATION FILED JULY 13, 190B.

' Patented Feb. 16, 1909.

Witnesses On the under side-of the plate are ivoted' two levers, ,16;'--e ach' having a cam ace-16 {adapted to lie; across itsadjacent slot, and to 'these levers are-pivotally connected a slide ilTwhich has a double cam facel7. adapted toiprojetzt into the recess t willreadily be-seen that when the foot pedal 4-is in theleft hand slot, upon-being .moved to the end 9f said slot it will engage the camface 17 lying across the recess and be shifted laterallyto the right. This lateral movement will throw arm 5 in the opposite direction and shifting'rod 1'() will be moved in the direction of the arrow, Fig. 3, through the medium of bell-crank lever 7, link 8 and lover 9 and the reversing gears' d, (5 will be moved into mesh withigears b,-c.

When the foot pedal 4 moves backward in the right hand slot the cam face 16 of the right hand lever 16 will be engaged by the foot edal'and the slide 17 will be moved to the right into the position shown in Fig. 2 and at the next forward movement of pedal 4 the left hand canrface 17 "of the slide will engage the pedalapd shift it to the left where upon the o crating mechanism and reversing gears will e moved in the opposite positionto that just described.

, When the forward driving gears are in mesh the reversing gears cannot be operated, and vice 'versa. When the gears b, b are moved to the left from the position shown, in Fig. 3, a pivoted spring-controlled hook 18 is automatically .moved' into engagement with a collar 10 on shifting rod 10, .thus locking the latter against "movement-to the left while. either of said gears is engaged. To release the collar from hook 18t12e rod E miist be moved to the right disengaging gears b", b whereupon a cam e on red E will move hook 18 away from collar 10. b

When the-shifting rod 10'is moved to the left to bring reversing gears d, d? into mesh, a spring-controlled hooklt) moves, into en .gagement. with asleeve. b on trod E preventing-said. rod from being moved to the left. When rod' 10 is again moved'l to the right a cam 13 on arm 13 engage hook 19 and .I'nov'es the -sameaway' from the sleeve b The operationof my invention has been sufficientlydescribed in connection with the I two parts pivoted together one part movable foregoing descriptionof form andarrangement .of parts to enable anyone to understand the same.

, 1 The combination-with a transmission mechanism, of a-clutchoperating member connected therewith,- means to; shift said 'memberlaterally to-ope'rate' said mechanism and'means operated by the movement, operate the shifting of said -member to e 2'. The combination with a transmission the. movements of the lever.

In testimony that I claim the mechanism, of aclutch operating member connected therewith, means to shift said member laterally to operate said mechanism and means operated by the movement of said member to automatically operate the shifting means.

3. The combination with a transmission mechanism, of a clutch operating member connected thereto, a cam to engage said member, and means 0 erated by'the movement of tlie la'tter to shift the cam.

4. The combination with a transmission mechanism having reversing gears, of a pedal connected with the reversing gearsthereof, a slide having cams thereon to im part a lateral movementto the pedal, and means operated by the movement of the pedal to'shift the slide for the purpose set forth.

- -5. The combination with a transmission mechanism having reversing gears and a clutch operating pedal connected with the reversin 'ears thereof of a'shiftin device b b J for the pedal comprising a slotted member in which the pedal moves, a slide at the end of the slots-saving cams thereon toshift the pedal from one slot to the other and cam members connected with the slide operated by' the movement of the pedal to shift said slide.

6. The combination with a transmission mechanism having reversing gearsand a pivoted lever connected with the reversing gears thereof, of a shifting device comprising a plate having parallel slots therein through which said lever projects said slots communicating at one end, a slide mounted at the communicatingend having two cam faces adapted to alternately engage the lever, and pivoted members connected to said slide having cams thereon adapted to lie in the path of the lever. V I

7. The combination with a' pivoted, lever, of a lever shifting device comprising a reciprocalile member having oppositely directed cam faces thereon, adapted to alternately engage said lever, and operating members connected with said reciprocable members adapted to be successively actuated by said lever.

8. The combination of a lever comprising relatively to the other and means to actuate the relatively movable part positionable by foregoing as my. invention, I have signed my name 1n presence of two subscribing w tnesses.
